Welcome Harish! That should be interesting to see the results of your
evaluation. I hope you will share that with the community once you
complete your research.

I haven't really done anything with HTTP/3, but from what I understand,
it just changes the transport to use QUIC. So that should be pretty
transparent as far as the OpenStack services are concerned.

We don't have any documentation that I know of. Unless someone has done
some of their own testing and has some notes they can share.

I think the main thing here would be just setting up nginx to use the
uWSGI apps rather than Apache. This seems like a promising article that
walks through configuring nginx:

https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-ubuntu-20-04

That specifically references flask, so just keep in mind that most
OpenStack services do not use that part of the tutorial.

Cinder has some old notes from when we were first looking at running
behind Apache. Those can be found here:

https://docs.openstack.org/cinder/latest/contributor/api.apache.html

But you may just need to look at the existing Apache configuration and
figure out what to change to do the equivalent under nginx.

Good luck!
